NEW JERSEY, A CORPORATON OF NEW YARN RACK.

Animation med .Tune as,

One object of my invention is to make a yarn rack in which the side members and upper and lower crossbars are made in a single structure, and which structure can. be suspended from the ordinary sticlocarrying i ame of a dyeing machine.

A further object of the invention is to so design the yarn rack that the yarn will be liree from Contact with all parts of the die Vat, with the exception oit the yarn rack.

In the accompanying drawings:

Fig. 1 is a perspective View of my improved yarn rack;

Fig. 2 `is an enlarged sectional View olf one side of the rack, showing details. of construction, and also showing the means by which the removable legs are attached to the rack;

Figs. 3 and 4 are perspective views illus-` trating details of the` construction of the fastenings for the legs;

Fig. 5 is a perspective View of the detached head of one of the legs of the raclA which are adapted to the recesses in the stick-carrying frame;

Fig. 6 is a View showing the rack` in the stick-carrying frame, a vat being shown by dotted lines; and

Fig. 7 is a View illustrating a modification oi the means for fastening the detachable legs to the body of the rack.

Referring to the drawing, 1-1 are the side members of the rack, connected together by an upper cross-bar 2 and a lower crossbar 3. This iframe is preferably made of Monel or other suitable metal which will not affect the yarn and. which will be smooth, as the invention is intended for use in dyeing Silks or rayons.

At the upper end of each side member is a head 4C having an extension 5 (Fig. 5) which projects :into the end of the tubular side member and is secured thereto by a pin or other fastening.

Une side member of the frame extends the full depth, while the other side member oli the frame terminates at fr, (Fig. l) and has an extension 6 in the form of a Jtubular leg as shown in Fig. 2; The upper end of this extension abuts against the lower end of the side member l as at ai, and secured Within the extension in the present instance is a tubular connecting member 7 which ein tends into the lower end oli the side member l of the frame.

192s. 'sei-iai no. 285,314.

The upper end oi the connecting member 7 has a bayonet slot 8 which engages a crossbar 9 extending across the member l oi' the fra-me, so that when it `is desired to attach the leg to the frame, all that is necessarier is to push the leg to the point where it coines in Contact with the end of the side member of the frame, and by turning it slightly it will engage the cross-bar 9, holding the leg rigidly in position. 0n the lower end di? each leg is a foot 10 which is secured to the leg by a pin as shown.

When it desired to place the yarn on the frame, the leg extension 6 is detached from the frame. This allows the skeins of yarn to be passed over the head of the side member and onto the cross-bars of `the frame. When all of the yarn is in place7 then the ieg 6 is coupled to the frame, thus insuring the yarn being held to the frame during the dyeing process, and by again detacliing the leg 6, the dyed yarn canbe :readily removed from the frame.

The heads of the trame are narrow so to lit into the ordinary stick 'recesses in the stick-carrying frame ll, the side members 12 of which are recessed, the recesses being spaced apart so that the yarn on one frame will not touch that on an adjoining trame. Y

The side members of the frame hold the yarn away from the sides of the vat, and. the crossdnars of the frame are located so that the yarn as it is raised oil' of the top cross-bar will not be entangled with the si de members ot theycarryiiig-iframe. l1"ui'i.lif \.r4 more, the heads fit the openings in the trame, so that it will be impossible :for any oi the material being dyed to come in contact with the vat or carrying-trahie, or enter the stiel: recesses when the die liquor is in circulation.

In Fig. 7 I have illustrated a modiicatimi7 in which the leg 6 has a threaded extension 7l adapted to the threaded end oi? the side member la.

I claim 1. A yarn rack for dyeing machines9 having side members and connecting upper and lower cross-bars; and detachable legs form ing a continuation of the side members below the` lower cross-bar.

2. A yarn rack for dyeing machines, having tubular side members and tubular upper and lower cross-bars; detachable tubular legs for-ming e Continuation of the side ineinbers below the, lower Cross-bar, said legs hayL ing portions arranged to extend Within the 5 tubular side members, said portions having' bayonet slots; and-a cross-bar in each side "member adapted' to befengaged by the said leg extensions. l

3. A yarn rack for dyeing machines, hav- 10 ng'side members and upper and lower erosc- Y bars, the side members extending above the upppelf crossfbzrr and lniying laterally extendingflared heads, `said heads beingr shaped to extend into recesses in the stiekezuifyi'ng frame of the dyeing machine.r the rack lla-ving ay leg at one side which can be detached when itv is desired' to alaee ya 11n on the rack or remove yarn therel'rorn.
